When the last edition of this book was published in 2000, the field
of proteomics was in its infancy. At that time, multidimensional
liquid chromatographic separations were being introduced as an
alternative to traditional gel-based techniques for separating
complex protein and peptide mixtures prior to mass spectrometric
detection. Today, this approach - referred to as shotgun proteomics
- is considered routine for lar- scale global analyses of protein
mixtures. Now in its adolescence, proteomics is fundamentally
transforming biological and medical research. Much of this
transformation can be attributed to technological advancements,
particularly in mass spectrometry. Much wider accessibility of hi-
resolution and mass measurement accuracy instrumentation in recent
years has ini- ated a new revolution in the field by providing more
reliable data and shifting the focus from cataloging proteins to
precisely quantifying changes in protein abundance over time and in
response to stimuli. Advanced mass spectrometers and novel ion d-
sociation schemes such as electron transfer/capture dissociation
make it possible to venture boldly into the maze of protein
posttranslational modifications, which are an integral component of
understanding functional proteomics in the spatial and t- poral
domains. Another area that has benefited from these advancements is
top-down proteomics, an emerging method essential for
characterizing various protein variants that has potentially high
impact in biomedical research.
